Commercial Humidifiers in Fullerton, CA

Engineered humidity for healthier, higher-performing buildings

As Fullerton’s dedicated commercial HVAC team, #1 AC Guys designs, installs, repairs, and maintains commercial humidifiers that stabilize indoor conditions and protect your people, products, and processes. Our 4th-generation, family-run company brings 80+ years of engineering know-how to every job, specializing in large and complex projects across offices, healthcare, manufacturing, printing, museums, schools, and data centers—right here in Fullerton and throughout Orange County.

Why precise humidity matters

Balanced humidity is essential for indoor air quality, comfort, and productivity. Too dry leads to static, material shrinkage, and virus transmission. Too humid encourages mold and corrosion. The right setpoint helps:
- Protect sensitive equipment and finishes
- Improve occupant comfort and well-being
- Stabilize production quality and yields
- Reduce particulate and pathogen spread
- Lower energy waste by enabling efficient temperature control

Systems and technologies we install

We match the right technology to your building’s load, utilities, and use case:
- Steam humidifiers: electrode, resistance, and gas-fired for robust output and tight control
- Ultrasonic humidifiers: low-energy, fine mist for precision spaces and labs
- Evaporative/media systems: efficient solutions for larger air handlers and make-up air
- High-pressure/atomizing options: targeted humidity with minimal energy use
- Duct-mounted and AHU-integrated configurations for even distribution
All systems can be designed with advanced sensors, airflow strategies, and staging to keep RH within ideal ranges while minimizing operating costs.

Factory-trained and brand-agnostic

Our engineers are factory-trained by leading manufacturers, including Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier. We are brand-agnostic and specify what best fits your application, budget, and timeline. That means you get reliable equipment, proven parts availability, and long-term serviceability.

Smart controls and BMS integration

We integrate seamlessly with your building management system for visibility and control:
- BACnet, Modbus, and open protocol integration
- Demand-based humidification tied to occupancy and process needs
- Coordination with VAV, ERV, economizers, and boilers/chilled water
- Alarm notifications, trend logging, and remote monitoring to reduce downtime

Design-first approach

Every humidification project starts with solid engineering:
- Full load and psychrometric analysis for Fullerton’s local climate
- Placement for even RH distribution and minimized stratification
- Water quality evaluation, filtration, and scale mitigation plans
- Drain, flush, and cleanliness cycles to maintain hygiene
- Code compliance, permits, and documentation handled end-to-end

Maintenance, repair, and lifecycle care

Our preventive service plans keep your commercial humidifiers reliable and efficient:
- Routine inspections, descaling, and electrode/cylinder replacement
- Filter and media changes, nozzle and dispersion tube care
- Sensor calibration and control sequence optimization
- Hygiene protocols to prevent biofilm and microbial growth
- Emergency repair and priority scheduling for contract clients
Consistent maintenance extends equipment life, preserves warranties, and protects your indoor environment year-round.
